The use of Clenbuterol (Clen) should always be recommended by a qualified medical practitioner as it is an extremely potent drug and may lead to side effects when abused or of a low grade.
Like all prescription drugs, Clen should always be purchased from a legal steroid store or pharmacy with a prescription and must be used only for legal or medicinal purposes. It should never be abused or overdosed in hopes of quick results as that can lead to side effects such as difficulty in breathing, gastrointestinal irritation, myocardial infarction, skin rash, urticaria, diaphoresis, nausea, tightness in the chest, vomiting, dizziness, depleted phosphate levels, dry mouth, insomnia, muscular shivering, cardiac hypertrophy, palpitation, potassium depletion, loss of concentration, frequent mood swings, and drowsiness.
Clenbuterol abuse may also cause health complications such as increased blood pressure, muscle cramps, excessive sweating, heartburn, face flushes, tremors, and restlessness and use of this drug is not recommended to those suffering from hyperthyroidism, tachycardia, tachyarrhythmia, heart or thyroid diseases, high blood pressure, coronary artery disease, congestive heart failure, prostatic hypertrophy, urinary retention, glaucoma, ischemic heart disease, myocardial infarction, and hypertrophic obstructive cardiomyopathy. People who are administered with antibiotics, Accutane, oral 17-alpha-alkylated steroids, or hepatotoxic (toxic to liver) elements should not use this weight loss drug and breastfeeding or lactating women and children should refrain from using this drug. Clenbuterol is best stored in a tightly closed container in a cool and well-ventilated area and at a controlled room temperature of 20° to 25°C (68° to 77°F) with excursions permitted to 15° to 30°C (59° to 86°F) besides protecting it against heat, moisture, direct sunlight, and sources of ignition.
